The invention discloses a sliding type dangerous rock mass identification method based on multiple indexes. The method comprises the steps that the initial cohesive force, the internal friction angle, the bonding length, the bottom face dip angle and the self weight of a rock mass to be identified and physical and mechanical parameters such as effective normal stress and shear stress on a sliding face are obtained; acquiring natural vibration frequencies and damping ratio parameters of the sliding type dangerous rock mass structure at different moments after damage; the cohesive force and the internal friction angle after damage are calculated; calculating a stability coefficient, a bonding stability coefficient and a cohesive force anti-sliding ratio index of the sliding type dangerous rock mass at different moments after the sliding type dangerous rock mass is damaged on the basis of the physical and mechanical parameters of the rock mass; on the basis of the stability coefficient, the bonding stability coe
